Three Alamance County stores sold alcohol to underaged buyers during a law enforcement operation Thursday tracking alcohol sales.

The Alamance Alcohol Law Enforcement Team found that most of the 20 stores its operatives attempted to purchase alcohol from complied with state laws Thursday, requiring identification and refusing to sell to underaged buyers.

Clerks at three stores — the Fairway One Stop, at 1382 S. Church St. in Burlington, Family Fare, at 301 S. Main St. in Graham, and the Marathon, at 807 W. Haggard Ave. in Elon — sold to underaged patrons.

North Carolina uses the Stoplight Driver’s License model: for those 15-17 the background border is red; for those 18-20 the background border is yellow. Both of those licenses are vertical. For those over 21, the background border is green and the license is horizontal.

In a release, Alamance Citizens for a Drug Free Community encouraged parents and adult to talk about alcohol with their children and asked retailers to be vigilant of underage buyers.

“We strongly encourage retailers to make sure their clerks are properly trained and follow the laws”, said Karen Webb with the Alamance Citizens for a Drug Free Community.
